To prepare meatballs, dice onion and saute in frying pan with 1 teaspoon of oil on medium heat, until onion begins to brown.

In a bowl, whisk egg, add breadcrumbs, mince and then onion and mix thoroughly. To prepare wholemeal breadcrumbs, freeze left-over bread. Once frozen, allow the bread to thaw for 5 minutes, and then place it in a food processor until crumbs form.
